Design of a gravity-flow water system in a remote community in Chiapas, Mexico. Open Practice has an ongoing interest in supporting indigenous communities in Latin America through the introduction of clean water systems and sustainable technologies.

Gravity-flow water systems use an existing source, typically a stream or a spring, within 3 kilometres of the community. The water is channelled into the ‘Captation Tank’ which feeds the mainline to the ‘Reservoir Tank’ built at a high point within the village. A distribution network is then designed to take fresh clean water to every house in the community, helping prevent the spread of Water Borne Diseases.
